摘要: 双碳"目标下,构建土地利用类型与碳转移的关系对碳减排至关重要。该研究以徐州市为例,提出了一个空间地-碳框架,运用生态网络分析(ecological net analysis,ENA)评估了土地相关碳的正、负转移及其生态关系的变化,提出用地-碳关联率评价土地利用变化对碳平衡的综合影响程度,并借鉴生态学种间关系的原理,探讨了碳流动下土地利用类型之间的生态关系。结果表明:2000-2010和2010-2020年,研究区主要正碳转移是耕地转换为工业与交通建设用地,主要负碳转移是工业与交通建设用地转换为城市建成区。随时间变化,碳转移强度增加,类型更加复杂;空间上,土地互利关系分布在下属区县,竞争关系分布在中心城区。碳转移推力、拉力贡献率分别来自耕地和工业与交通建设用地。地-碳框架量化了土地相关碳转移,探明了各土地利用类型之间的生态关系,为碳排放空间规划提供了新视角。

Abstract: For achieving the national "Dual Carbon" target, urban emission reduction is imminent. In this study, a spatial land-carbon framework was proposed. Taking the land use type migration in Xuzhou city from 2000-2010 and from 2010-2020 as example, The Ecological Network Analysis (ENA) was used to evaluate the positive and negative transfer of land-related carbon emissions and the changes of Ecological relationships. The land-carbon correlation rate was proposed to evaluate the comprehensive impact of land use changes on carbon balance in Xuzhou city. The interspecific ecological network between land use type conversion and carbon transfer was discussed based on the interspecific mechanism of ecology. The results show that:(1) the main positive carbon transfer was from cultivated land to industrial and transportation construction land, and the main negative carbon transfer was from industrial and transportation construction land to urban built up area. (2) In terms of time, carbon transfer intensity increased and the transfer type became more complex. In terms of space, the mutually beneficial relationship of land is distributed in subordinate districts and counties, while the competition relationship is distributed in central urban areas. (3) The contribution rate of carbon transfer thrust is mainly from farmland and the contribution rate of carbon transfer pull is mainly from industrial and transportation land. The land-carbon framework quantifies the land-related carbon transfer and obtains the ecological relationship between different land use types, which provides a new perspective for the spatial planning of carbon emissions.

Key words: land-carbon framework, ecological network analysis, land use change, carbon transfer, Xuzhou
